Taiko has announced a significant upgrade to its mainnet protocol, Taiko BCR, which will be effective on July 1. The new version, 1.7.0, is designed to improve the efficiency and security of the protocol, ensuring a better user experience. The upgrade is compatible with the current Taiko-geth and client version ABI but introduces underlying changes that affect block proposers and validators.

The key updates in version 1.7.0 include changes to the block proposal and validation process. Specifically, the designated validator of a block must also be the proposer, and block validators need to verify the stateRoot of existing conversions. Additionally, the validity and dispute guarantees of the liveliness guarantee and SGX proof have been reduced by 50%. Gas optimization has also been implemented to improve the protocol's performance.

The upgrade also includes an upgrade to the Hekla testnet protocol, which may cause some block proposal and proof transactions to fail. Therefore, all Hekla block proposers and validators are advised to update their transaction parameters as soon as possible. The changes in version 1.7.0 are expected to enhance the overall efficiency and security of the Taiko BCR mainnet protocol, ensuring a smoother user experience.

Taiko's decision to upgrade its mainnet protocol demonstrates its commitment to continually improving its blockchain technology. The changes in version 1.7.0 are designed to improve the protocol's performance, security, and usability, aligning with Taiko's goal of providing a robust and efficient blockchain platform.

The upgrade to version 1.7.0 is a significant step forward for Taiko, showcasing its dedication to innovation and excellence in blockchain technology. As the blockchain landscape continues to evolve, Taiko's commitment to improving its protocol ensures that it remains at the forefront of the industry, providing a reliable and efficient platform for users.
